Punisher and Daredevil doesn't need a lot of explanation, as they can function in the cinematic Marvel world.
But Blade? That means vampires do exist. How come SHIELD don't keep track of them?
And Ghost Rider? Holy fried beans. Satan and Hell are real too. I don't see how that could possible work.
Would Lucifer be an actual fallen angel? Or would he just be a cosmic being, much like Thor, Odin and Loki?
